For other kinds of stress, see Stress. In psychology, stress is a feeling of strain and pressure. Stress can be external and related to the environment, but may also be caused by internal perceptions that cause an individual to experience anxiety or other negative emotions surrounding a situation, such as pressure, discomfort, etc. When people think the demands being placed on them exceed their ability to cope, they then perceive stress. A very much overlooked side of stress is its positive adaptations. Positive psychological stress can lead to motivation and challenge instead of anxiety. The effects of experiencing eustress, which is positive stress, versus distress, which is negative stress, are significant.
Selye proposed that there are four variations of stress. The goal is to balance these as much as possible. Eustress is when a person perceives a stressor as positive. There is likely a connection between stress and illness. Stress can make the individual more susceptible to physical illnesses like the common cold.
Stressful events, such as job changes, may result in insomnia, impaired sleeping, and health complaints. This is particularly true regarding chronic stressors. Studies have also shown that perceived chronic stress and the hostility associated with Type A personalities are often associated with much higher risks of cardiovascular disease. This occurs because of the compromised immune system as well as the high levels of arousal in the sympathetic nervous system that occur as part of the body’s physiological response to stressful events. It has long been believed that negative affective states, such as feelings of anxiety and depression, could influence the pathogenesis of physical disease, which in turn, have direct effects on biological process that could result in increased risk of disease in the end. Experiments show that when healthy human individuals are exposed to acute laboratory stressors, they show an adaptive enhancement of some markers of natural immunity but a general suppression of functions of specific immunity.
By comparison, when healthy human individuals are exposed to real-life chronic stress, this stress is associated with a biphasic immune response where partial suppression of cellular and humoral function coincides with low-grade, nonspecific inflammation. Even though psychological stress is often connected with illness or disease, most healthy individuals can still remain disease-free after confronting chronic stressful events. Also, people who do not believe that stress will affect their health do not have an increased risk of illness, disease, or death. As stress has a physical effect on the body, some individuals may not distinguish this from other more serious illnesses. In animals, stress contributes to the initiation, growth, and metastasis of select tumors, but studies that try to link stress and cancer incidence in humans have had mixed results. This can be due to practical difficulties in designing and implementing adequate studies.
It is neutral, and what varies is the degree of response. It is all about the context of the individual and how they perceive the situation. A stressor is any event, experience, or environmental stimulus that causes stress in an individual. These events or experiences are perceived as threats or challenges to the individual and can be either physical or psychological. Stressors are more likely to affect an individual’s health when they are “chronic, highly disruptive, or perceived as uncontrollable”.

This type of stressor is unforeseen and unpredictable and, as such, is completely out of the control of the individual. Common examples of major life events include: marriage, going to college, death of a loved one, birth of a child, moving houses, etc. These events, either positive or negative, can create a sense of uncertainty and fear, which will ultimately lead to stress. The length of time since occurrence and whether or not it is a positive or negative event are factors in whether or not it causes stress and how much stress it causes. Researchers have found that events that have occurred within the past month generally are not linked to stress or illness, while chronic events that occurred more than several months ago are linked to stress and illness and personality change. This category includes daily annoyances and minor hassles.
Examples include: making decisions, meeting deadlines at work or school, traffic jams, encounters with irritating personalities, etc. There are three major psychological types of conflicts that can cause stress. The approach-approach conflict, occurs when a person is choosing between two equally attractive options, i. The avoidance-avoidance conflict, occurs where a person has to choose between two equally unattractive options, for example, to take out a second loan with unappealing terms to pay off the mortgage or to face foreclosure on one’s house.
